As used herein, a reference numeral refers to a class or type of entity, and any letter following such reference numeral refers to a specific instance of a particular entity of that class or type. Thus, for example, a hypothetical entity referenced by ‘12A’ may refer to a particular instance of a particular class/type, and the reference ‘12’ may refer to a collection of instances belonging to that particular class/type or any one instance of that class/type in general.

In one or more embodiments, one or more components of an information handling system may be cooled. For example, heat may be removed from one or more components of an information handling system. In one or more embodiments, a liquid may be utilized to cool one or more components of an information handling system. For example, a liquid may be utilized to remove heat from one or more components of an information handling system. In one or more embodiments, a liquid utilized to cool and/or remove heat from one or more components of an information handling system may include a mixture of liquids. For example, the mixture of liquids may include a mixture of water (H₂O) and glycol. For instance, the mixture of liquids may include a mixture of seventy-five percent (75%) water and twenty-five percent (25%) propylene glycol.

In one or more embodiments, if a leak of a liquid utilized to cool and/or remove heat from one or more components of an information handling system occurs, one or more portions of the information handling system may be damaged. In one example, the one or more portions of the information handling system that may be damaged may include the one or more components of the information handling system.

In another example, the one or more portions of the information handling system that may be damaged may include one or more circuit boards of the information handling system.

In one or more embodiments, the liquid utilized to cool and/or remove heat from one or more components of the information handling system may cause one or more short circuits. For example, the one or more short circuits may damage the one or more portions of the information handling system. In one or more embodiments, the liquid utilized to cool and/or remove heat from one or more components of the information handling system may cause one or more corrosions. In one example, the one or more corrosions may damage the one or more portions of the information handling system. In another example, the information handling system may not function properly due to the one or more corrosions. In one or more embodiments, the leak of the liquid utilized to cool and/or remove heat from the one or more components of an information handling system may be caused by one or more of vibrations, thermal cycles, aging, oxidation, junction sealant decay, and pests, among others.

In one or more embodiments, the liquid utilized to cool and/or remove heat from one or more components of the information handling system may include water. For example, the water may not include low levels of electrolytes or may include low levels of electrolytes. For instance, the liquid may not be a good conductor of electricity. In one or more embodiments, an electrolyte may include a substance that produces an electrically conducting solution when dissolved in a polar solvent. In one or more embodiments, if the liquid leaks onto a detection circuit that measures electrical conductivity, it may be difficult to determine a leak of the liquid via electrical conductivity, as the liquid may not be a good conductor of electricity. In one or more embodiments, if one or more electrolytes are added to the liquid, the one or more electrolytes may promote and/or accelerate liquid leaks. For example, if one or more electrolytes are added to the liquid, the one or more electrolytes may promote and/or accelerate one or more of aging, oxidation, and junction sealant decay, among others.

In one or more embodiments, a device that may be utilized to determine a leak of the liquid via electrical conductivity may include multiple conductors and a material that includes a substance that forms an electrically conductive solution when dissolved by a polar solvent. In one or more embodiments, the polar solvent may be or include water. For instance, a dissolved substance that forms an electrically conductive solution when dissolved by a polar solvent may separate into cations and anions. For example, the dissolved substance may be or include an electrolyte. In one or more embodiments, if an electric potential is applied to the dissolved substance, the cations may be drawn to a first electrode that has an abundance of electrons and the anions may be drawn to a second electrode that has a deficit of electrons (e.g., holes). For example, movement of the anions and the cations in opposite directions within the dissolved substance may amount to a current. In one or more embodiments, an electrolyte may include a substance that may dissociate into ions in solution and may acquire a capacity to conduct electricity. For example, an electrolyte may include one or more of a soluble salt, an acid, and a base, among others.

In one or more embodiments, the liquid utilized to cool and/or remove heat from one or more components of the information handling system may leak and may travel to the device that may include multiple conductors and a material that includes a substance that forms an electrically conductive solution when dissolved by a polar solvent. For example, the liquid and the substance of the material may form the electrically conductive solution that may conduct electricity among or between the multiple conductors of the device. For instance, a resistance value between two conductors of the device may be lower when the conductors of the device are exposed to the electrically conductive solution that includes the liquid and the substance. In one or more embodiments, the material that includes the substance that forms the electrically conductive solution when dissolved by the polar solvent may not be hygroscopic. In one or more embodiments, the material that includes the substance that forms the electrically conductive solution when dissolved by the polar solvent may be porous.

In one instance, the pores may permit the liquid to permeate the material that includes the substance that forms the electrically conductive solution when dissolved by the polar solvent. In another instance, the pores may permit the liquid to be transferred to the conductors of the device. In one or more embodiments, the pores may transfer the liquid to one or more of the electrolyte and the conductors of the device via capillary action. In one example, the capillary action may transfer a solution of the liquid and the substance that forms the electrically conductive solution when dissolved by the polar solvent to the conductors of the device. In another example, the capillary action may mix the liquid and the substance that forms the electrically conductive solution when dissolved by the polar solvent to form a solution of the liquid and the substance. For instance, the capillary action may cause the liquid and the substance to form the solution of the liquid and the substance and may transport the solution of the liquid and the substance to the conductors of the device.

In one or more embodiments, the device that includes the conductors and the material that includes the electrolyte may be placed in an area where a leak of the liquid is likely to occur. In one or more embodiments, the device that includes the conductors and the material that includes the electrolyte may be placed in an area where detecting a leak of the liquid is important. In one or more embodiments, the device that includes the conductors and the material that includes the electrolyte may be fastened to the area. For example, the device may include a fastener.
